IAEA report: Iran tested advanced nuclear warhead design

Portions of an IAEA report that were previously unpublished show evidence that Iran may have experimented with a more advanced nuclear warhead than thought. The news comes as talks with the West have largely stalled.

The Guardian writes that while Tehran has dismissed much of the IAEA's evidence of Iranian nuclear-weapon technology, it did admit that it has experimented with creating multiple, synchronized explosions of the kind that could trigger a nuclear device. The technology that the IAEA's documentation indicates Iran is testing would be a step beyond such experiments.

News of Iran's possible advanced warhead experiments comes as talks between Iran and the West have appeared to have stalled. The Washington Post reports that a senior European diplomat says Iran has demanded immediate delivery of substitute nuclear fuel if it agrees to surrender its own uranium, but the West is insisting the original deal be followed.
